Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
Description
The Okta RADIUS Agent does not validate the sub-attribute length when parsing a Vendor-Specific attribute. A sub-attribute length of zero causes the parser to loop indefinitely, resulting in worker-thread exhaustion and denial of new RADIUS authentication requests.
